4-54. an article in the asce journal of energy engineering (vol. 125, 1999, pp. 59–75) describes a study of the thermal inertia properties of autoclaved aerated concrete used as a building material. five samples of the material were tested in a structure, and the average interior temperature reported was as follows: 23.01, 22.22, 22.04, 22.62, and 22.59. (a) test the hypothesis versus using use the p-value approach. (b) check the assumption that interior temperature is normally distributed. (c) find a 95% ci on the mean interior temperature. (d) what sample size would be required to detect a true mean interior temperature as high as 22.75 if we wanted the power of the test to be a least 0.9
